Wins are a team stat...
Everybody wants to win, but if we are talking about what we want in a QB, it is ideal to have QB production that helps beat the better teams in the league...because unless your defense is the 85 Bears or 00 Ravens, sub par QB production will not be enough...
So, with our defense, Derek Carr stats would make us Super Bowl contenders...less than that and we are just wild card contenders...
I would also add our wild card game...with the amount of attempts Josh had in that game, had he thrown for 300 yards, Bills likely win...
